General Description
The HMC747LC3C is a D-Type Flip-Flop designed to
support data transmission rates of up to 14 Gbps, and
clock frequencies as high as 14 GHz. During normal
operation, data is transferred to the outputs on the
positive edge of the clock. Reversing the clock inputs
allows for negative-edge triggered applications.
All differential inputs to the HMC747LC3C are CML
and terminated on-chip with 50 Ohms to the positive
supply, Vcc, and may be AC or DC coupled. The
differential CML outputs are source terminated to 50
Ohms and may also be AC or DC coupled. Outputs
can be connected directly to a 50 Ohm Vcc-terminated
system, while DC blocking capacitors may be used
if the terminating system is 50 Ohms to ground. The
HMC747LC3C also features an output level control pin,
VR, which allows for loss compensation or signal-level
optimazation. the HMC747LC3C operates from a single
3.3 V supply and is available in ROHS-compliant 3x3
mm SMT package.
